Learn dyadic wavelet transform for image enhancement with practical examples demonstrating non-linear enhancement techniques, including implementation approaches and key algorithm considerations.
Detailed Documentation
This example demonstrates how to apply dyadic wavelet transform for image enhancement. The method proves highly effective for achieving non-linear enhancement effects through multi-scale decomposition. The implementation typically involves wavelet decomposition using dyadic scales (powers of 2), followed by non-linear processing of wavelet coefficients before reconstruction. Key functions may include wavelet filter bank design, thresholding strategies for coefficient modification, and inverse transform operations. This practical example helps deepen understanding and application of dyadic wavelet transform techniques in digital image processing.
